The thicknessof. e it retaining flange 1% is-less than e hem tal dimension of the chamber groove"9*- m mosa so that the wheel hub is relieved of bearing thrust and of wear at the faces of this flange 12.

When it is desired to put one of the wheels and the adjacent part of the axle in proper position relatively to the bearing, thelbolts .8, Bare withdrawn, and the axle 1 is moved upwardly between the flanges-7, 7 into the through the-straight .or chamber in the en argement 9 until it Is bearing .face .of the box 2.

osition shown in Fig. 1 (or, vice-vers'a, the earing is let down over the axle) ,the flange 12 at the same time sliding bodily upward arts 9 of'the groove seated loosely inthe upper part 5) of? the chamber.

Within each hub there is a bushing 14 which fitsaround the end part of the shaft snugly, and also fits inside of the wheel hub -10. The inner end of the bushing is formed with projections or lugs 15,. preferably of the nature of sections of a circular periphera] flange. The inner end of the wheel hub 10 is correspondingly formed with recesses or sockets 17 of a peripheral length slightly greater than that of the projecting flange sections 15; When the bushing isin place these bushings fit in the iecesses in the=end ofthe hub and the bushing'and wheel are locked together so that the former rotates .with the'latter. But the, inner end of the bushing bears against the outer vertical I The thrust against the box is first taken by a washer 19,

which entirely surrounds the --axle,- and therefore closes the gap or opening between the flanges 7, 7 and just below the axle.

' rail tree The lubricant in the chamber 15 passes to the inner wearing surfaces of the bushing through the passages or ports 25-,- and from theseit-is carried along the aide to the end 1 thrust surfaces of the bushing.

It will be seen that under ordinary circumstances, aiid jwhile the car is moving .in straight lines, each wheel, with its bushing 14, rotates upon the end part of. the axle. If'at any instant there. is aslightcramping of the bushing against the side, the latter can rotate in its-bearings. It will also be seen that if the track swerves from a straight "line the flange 21 of the wheel which is onthe outefl -cur ve be] (ii-said: wheelto its bushing, fan it.-is..,then

transmitted through the wheel hub and the-Y.

wheel to the rail.- The axle, havin -no engagement, along axial lines, with eit er that wheel or,its,bearing-.(and, for that matter, having no engagement the ,opposite .wheel or its tearin );smu 1- v,

. the more expensive elements of the structure are relieved, the nexpensive bushing cast-' ins to bearagainst the 20,1and t 1e inertia of th'e car and its .load'tran'smits pressure throu h the box places other thanthe warm bushing of the wheel on t 0 Outer eum;

'lhoaxle is'free to not only; 1,'ytilt0 .blltyl' jo move endwise, if necessary, both 'ifi'the" wheels and in the bearings. As all. oi the wear resulting from lateral pressure from the ear bearing, and also all of the wear, I

practically, caused by the rotation Jot the wheel on the axle, are/taken by the'busliings,

ings bring the only parts that require replacing.

.\s above reinarlwd, thewlieel hub being a tube which is tightly closed at all parts 'except at its inner end, it is" impossible for wearing or abrading particles to gain fentrance to the wearing surfaces.

' Whatl claim is:

1. The herein described wheel mounting for a. coal mine car, having in combinz'ition the car body, the liraring securedthereto,- the round rod axle mounted loosely-"1n the.

bearings and adapted to more longitudinally therethrough, the wheels ea'rh loose upon and tightly. im-losiug an end of the axle, noun-rotary devices carried bythe our body engaging with thoiwhorl to hold it longitudinally, and the bushing between the axle and the wheel-and interloekihg with the latter and beariiw against the bearing box 2. The hereinfiosrribed wheel mounting for a coal mine car haying in conibination the body, the bearing box secured thereto having the upper part adapted to rest upon the axle, the downwardly extending axleghidii'ig and holding flanges and an integral laterally acting wheel retainer, the axle mounted loosely in the bearing box "and adapted to be moved transversely toits axis on vertical lines between the said guiding and holding flanges into and. out of working position in the bearing box, the wheel loosely. mounted on and inclosing the end of tlie ll-XlG and 'fii'rined with a hub having an integral -.whee1-retainin g. devicet'o engage the retaining device on the bearing, and a bushing tube loosely" fittedj within the hub -'and interlocking. therewith, the hub and.

bushingbeing adapted to bear. against the box an flanges thereon- In testimony whereof, I aff x inygsignae ture, in presence of two witnesses.
